Despite the dribs and drabs of information, the foldable phone's brief onstage appearance raised more questions than answers. Here's what we know -- and what's still to come.

Samsung didn't give the foldable phone a name, but rumors suggest that it'll be called the Galaxy X or Galaxy F. The "F" could stand for "fold" or "flex". The "X" might mean "extra" or "10", since there are 9 Galaxy S phones out -- though we do expect to see a Galaxy S10 around March this year.
